Kevin Costner’s Ex-Wife Confirms Relationship with Mutual Friend Josh Connor

Christine Baumgartner isn’t keeping her romance with Kevin Costner‘s former friend a secret anymore … shamelessly holding hands in Montecito months after finalizing her divorce.

The actor’s now-ex-wife stepped out with financier Josh Connor Tuesday — walking out hand-in-hand in public … while rocking sporty attire for a stroll around the ritzy SoCal town … and they’re not shying away from the PDA here.

There wasn’t any kissing as far as we can tell … but CB and JC were all over each other, hand-holding and even wrapping their arms around each other’s waists.

Of course, rumors about Christine and Josh were swirling just months after Christine filed for divorce last May — when they went on a Hawaiian vacation in July. Sources connected to the Costner divorce said the two were just friends at the time … although, some called BS.

Baumgartner later made similar statements in court … claiming she didn’t go on a romantic trip with Josh — although it seems their relationship’s pretty dang romantic these days!

Christine and Kevin put the final touches on their divorce in February … ending one of the messiest Hollywood splits in recent history. Settlement details weren’t revealed at the time, but we know a judge validated the contentious prenup.

BTW … the exes asked for joint custody of their three children — and, a court ruled Baumgartner should receive a hefty $63k in child support from the Yellowstone actor. Ultimately, looks like Christine and Josh moved out of the friend zone … and now, they’re letting the whole world know it.
